1. Product Introduction
Aluminum foil ceramic fiber paper combines flexible insulation, infrared reflection, and dust-proof sealing in one material. It is suitable for thermal management, fire protection, insulation, and sealing applications in industrial high-temperature environments. It performs particularly well in scenarios requiring strict control of thermal radiation and dust cleanliness.
The product is asbestos-free, has low bio-persistence, and complies with EU ROHS and REACH environmental standards, making it an upgraded alternative to traditional refractory fiber paper.
2. Product Structure & Working Principle
✅ Base Layer: High-purity ceramic fiber paper, providing excellent thermal insulation, high-temperature resistance, and flexibility.
✅ Composite Layer: Industrial-grade aluminum foil, reflecting thermal radiation, enhancing wind erosion resistance, and providing dust and moisture protection.
✅ Bonding Method: High-temperature resistant inorganic adhesive ensures strong bonding under extreme thermal conditions.
In high-temperature environments, the aluminum foil layer reflects over 90% of infrared radiation, while the ceramic fiber substrate absorbs and blocks heat conduction. The synergistic effect of both layers significantly reduces heat loss and improves overall insulation efficiency.
3. Performance Advantages
（1）High-Temperature Resistance: Continuous operating temperature up to 1000°C, short-term exposure above 1100°C.
（2）High Reflectivity: Aluminum foil efficiently reflects infrared heat, lowering surface temperature.
（3）Lightweight & Flexible: Easy to cut, wrap, and adhere, suitable for complex structures.
（4）Dust-Proof Sealing: Dense surface prevents fiber shedding, ensuring cleanliness.
（5）Environmentally Friendly & Safe: Asbestos-free, low dust, non-irritating to skin and respiratory system.
（6）Chemical Stability: Resistant to most acids and alkalis, excellent thermal shock performance.
